CONCRETE WALL coNsTnUo'rIoN.

Application led April 5, 19524. Serial No. 704,353.

To all whom z't may concern.'

Be it known that I, ARTHUR G. HATCH, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain now and useful Improvements in Concrete Wall Constructions, of which the following is a speciication.

This invention relates to a new and improved wall construction and more particularly to a construction involving adjacently placed wallswith tying means connecting the two walls. v

In certain t pes of walls, in order to have increased stability and insulating effect with a minimum of concrete or other wall material, the walls are formed of two spaced walls which are tied together. This tying together is essential in order to preserve the strength and stability of the wall.

With double walls of this character it is extremely diiiicult' to maintain the joints between the blocks in the two walls directly opposite. Due to the slight variation in the lengths of blocks and also due tov sliglt variation in thickness of mortar joints tween blocks there will not be exact registrati-on. These errors may more or less compensate throu hout the wall so that the joints are su stantially opposite, but in stretches of wall of considerable area cumulative error is likely to occur, such as to y cause a marked lack of registration in some portions of the wall.. This lateral displacement renders impractical the use of tie blocks as generally constructed making closely fitting right angle joints with the wall blocks. i

It is -an object of the present invention to provide a new and improved wall coi1- struction whereby adjacent walls may be tied together without exactregistration of block joints.

It is a further object to provide a construction of this character using-blocks of simple design and without special forms.

Other and further objects will appear as the description proceeds.

I have illustrated a preferred embodiment of my invention in the accompanying drawings, in which- Figure 1 is a plan view of the section of wall showing the joints on the opposite walls in registration; and

Figure 2 is a view similar to Figure 1 but showing the wall joints laterally displaced relative to each other.

The wall construction comprises a pair of spaced walls 11 and 12, the wall 11 beingV .formed of a plurality actly similar recesses.

The tie blocks 20 are provided with the enlarged heads 21 and, as shown, are pro vided with the metal reinforcements 22.

The heads 21 of the blocks 2 0 are considerably smaller than the recesses formed byA the ends of adjacent blocks. As shown in the drawings, the thickness of the body portion of the block 2O is substantially equal to the distance between the portions 18 of the recessed end faces of the blocks.

As shown in Figure 2, the configuration of t the recess is such as to ermit the tie blocks tobe put in place although there is con# siderable displacement between the joints on the opposite walls. -It will be understood that when the tie block is put in lace the remainder of the recess will be fille with the mortar 23. It will be noted that both of the faces of the wall are formed only of the main blocks, the tie blocks not extending to these faces.

I have illustrated one preferred form of construction but my invention is obviously adapted for use with blocks of differing conguration and I contemplate such changes and modifications as come within the scope of the appended claims.

I claim:

1; In a wall construction, a pair of op sitely placed walls vformed of wall bloc s, opposed recesses formed in the ends of juxtaposed blocks, vtie blocks connecting the two walls, the tie blockshaving enlarged ends fitted in the recesses formed between the adjacent blocks, the ends Ibeing smaller than the recesses whereby the tie locks may be angularly disposed to connect walls having the block 'ointslaterally displaced relative to each ot er.

2. In a. wall construction, a pair of op-positely placed walls formed of Wall blocks, opposed recesses formed in the ends of juxtaposed blocks, the recesses having large inner portions and reduced portions communicating with the inner faces of the Wells, tie blocks connecting the two walls, the tie blocks having enlarged ends fitted in the recesses formed between the adjacent blocks, the ends being smaller than the recesses 'whereby the t1e blocks may be angularly disposed to connect Walls having the block joints laterally displaced relative t-o each other.

3. In a Wall construction, e pair of oppositely placed Wells formed of wall blocks,

1,sov,es1

opposed recesses formed in the ends of juxtaposed blocks, the recesses having large inner portions and reduced necks and tiaring openings communicating with the inner faces of the Walls, tie blocks connecting the two Walls, the tie blocks having enlarged ends fitted in the recesses formed between the adjacent blocks, the ends being smaller than the recesses whereby the tie blocks may be angularly disposed to connect walls having the block joints laterally displaced relative to each other.

Signed at Duluth, Minn., this 20th day of March, 1924.
